Inverse problems for linear degenerate parabolic equations by “time-like” Carleman estimate

In this paper, we study inverse problems for multi-dimensional linear degenerate parabolic equations and strongly coupled systems. In particular we discuss the Lipschitz type stability results for the inverse source problems which determine a source term by boundary data on an appropriate sub-boundary and the data on any fixed time. Our arguments are based on the Carleman estimate. Here we prove and use the Carleman estimate with the x-independent weight function for linear degenerate parabolic equations and systems.

Keywords: Carleman estimate; inverse source problem; conditional stability; uniqueness; linear degenerate parabolic equation
